IMPROVEMENT IN SPINNING-MACHINES FOR SPOTTING AND COVERING YARN.

Specification forming part of Letters Patent No. 208,622, dated October 1, 1878 application filed June 10, 1878.

To all whom it may concern:

Be it known that I, WALTER MoVrLLA, of Manayunk, in the city of Philadelphia and State of Pennsylvania, have invented a new and useful Improvement in Spinning Machines for Spinning Spotted and Covered. Yarns, of which the following is a specification:

The invention relates to improvements in" spinning-machines in which the spotting or covering fibers are applied to the body-yarn as it is being spun; and the invention consists in the combination and arrangement of a series of rollers for delivering the spotting-fibers with the rollers that draw and deliver the fibers from which the body-yarn is spun, all as will be hereinafter described, referring to the drawings, in Which Figure 1 is a top view of my improved ma- Figs. 2 and 3 are views of the rollers used to deliver the spotting-fibers to the bodyyarn. Fig. 4 is a view of the pin on which the roller D revolves. Fig. 5 is an end view of Fig. 1. The rollers and roller-beams are shown in section. taken on one of the dotted lines of Fig. 1. Fig. 6 is an end view of crank and pawl for operating the rollers O and 0.

Similar letters in the drawings refer to like parts.

The construction of my improvement is as follows: A A A represent the top, and B B B the bottom, rollers; M, the roller-beam, and W the wire board of the ordinary cotton spinning frame. These parts are constructed and operated as is usual in cotton-spinning machines.

Restin g on the wire board W, and fastened to the beam M, is aroller-beam, E. To this beam E are fastened two pillars, F F, in which is supported the shaft S. 011 this shaft are two bevel-wheels, a a, which gear into the bevel-wheels b b, connected to the spur-wheels (1 d, and working on studs fastened to beam E. In the roller-beam E are two stands or journal-steps, ff, (see Fig. 5,) in which work rollers O G. On the end of roller 0, to the right, is a ratchet-wheel, H.

Above the rollers O O, and placed at right angles to them, are the rollers D D. On one end of roller D is a small pinion-wheel, e. The roller D is fitted to revolve on the pin g.

The rollers A A A, O, and D are covered with leather. The rollers B B B, G, and D are fluted.

On the end of the front roller, B, to the right,

is an adjustable crank, J, to which is connected a pawl, K.

The operation of my improvement is as follows: Motion is communicated to front roller, B, which operates the crank J pawl K, and wheel H, which latter, in turn, communicates an intermitting rotary motion to rollers O O, and the front roller, B, by the wheel L, drives the shaft ,S, and this, by the bevel-wheels a and b and spur-wheels cl and 6, drives the rollers D D, imparting a continuous rotary motion thereto.

P represents a white roving, which is fed through the frame in the usTial manner, and is twisted into yarn as it leaves the front rollers.

It represents a black roving, which passes through a hole in the roller-beam E, and between the rollers O O and D D, which rollers O O, as before described, have an intermitting motion imparted to them, and the rollers D D a continuous motion, thus causing the black fibers to be broken from the roving R at regular intervals.

The yarn T receives a revolving motion as it is being twisted, and the black fibers from the roving It are lapped around the white yarn, showing well-defined spots at regular intervals, which may be regulated by the crank J, pawl K, and wheel H.

As the yarn is formed, it is wound on a bobbin in the usual manner.

It is understood that, in practice, the gears are covered by a tin or cast-iron box.

I am aware that spotted yarn has been spun on a spinning-machine, in which machine the spotting-fibers were delivered to the bodyyarn by a pair of rollers having an intermitting motion imparted to them. This I do not claim; but,

As my improvement, I claim 1. The rollers D D, arranged at right angles to the main delivery-rollers and transversely above the auxiliary set of deliveryrollers, in combination with the rollers G G, as shown and described, and for the purpose specified.

2. The combination of rollers D D and O O with the delivery-rollers A B of a spinningmachine, as shown and described, and for the purpose specified.
